Constructor Detail

Dyadic

public Dyadic(Graph L,
              Graph R)

When the graph is constructed, copy the prefix mappings of both components into this prefix mapping. The prefix mapping doesn't change afterwards with the components, which might be regarded as a bug.

Method Detail

close

public void close()

Description copied from interface: Graph

Free all resources, any further use of this Graph is an error.

Specified by:

close in interface Graph

Overrides:

close in class com.hp.hpl.jena.graph.impl.GraphBase

dependsOn

public boolean dependsOn(Graph other)

Generic dependsOn, true iff it depends on either of the subgraphs.

Specified by:

dependsOn in interface Graph

Overrides:

dependsOn in class com.hp.hpl.jena.graph.impl.GraphBase

Parameters:

other - the graph this graph may depend on

Returns:

false if this does not depend on other

union

public Union union(Graph X)

getL

public java.lang.Object getL()

Answer the left (first) operand of this Dyadic.

getR

public java.lang.Object getR()

Answer the right (second) operand of this Dyadic.
